Question

Write any three important properties of metals and non metals

Answer 1

three important properties of metals are: 1.sonorous
                                                                 2.lusturous
                                                                 3.hardness
three important properties of non metals are: 1.not very hard
                                                                        2.are bad conductor of                                                                                           heat&electricity
                                                                        3.do not produce sound

Answer 2

Metals
1. They react with Oxygen to make basic oxides.
2. They react with water to form Metal oxide or Metal hydroxide.
3. They react with acids to give Hydrogen gas.
4. They are electropositive.

Non metals

1. They react with Oxygen to form acidic oxides.
2. They are generally poor conductors of heat. ( except graphite)
3. They are electronegative.




Physical properties are not considered because they have many exceptional cases.
